The ball drops 72 inches (6 feet).
The ball bounces back 49 inches (4 feet, 1 inch).
49/72 = 68.05%
So yes, the ball (barely!) passes inspection.
The answer would be 18.2 gallons because they used up 5.8 gallons, they still have 12.4 gallons that they did not use and in order to get the original amount of gas they had before the trip, you would add up 12.4 and 5.8 to get the Original amount. Hope this helps.
The value of x+y+z = 93
<u>Explanation:</u>
<u></u>
angle 1 = 18x
angle 2 = x+y
angle 3 = 30z
In rhombus, the diagonals intersect at 90°
Therefore,
angle 1 : 18x = 90
x = 90/18 = 5
angle 2: x+y = 90
5+y = 90
y = 85
angle 3: 30z = 90
z = 90/30 = 3
Value of x+y+z = 5+85+3 = 93
Thus, the value of x+y+z = 93
4) 41% of 78 is what?
Answer = 31.98
Work:
x = 41/100 x 78
x = 3198/100
x = 31.98
6) 58% of what is 63.4?
The number is = 109.31
Explanation:
Let the number be = x
58/100 (x) = 63.4
x = 63.4 x (100/58)
x = 6340/58
x = 109.31
